TO ALL WHGM IT MAY CONCERN:

Be it; known that CHARLES E. RUSSELL, ofJaeksonville, in the county of Morgan, and in the State of Illinois, have invented certain new and useful improvements in Heat Rndintors; nud do'hcreby declare that the following is n` full, clear, and exact description thereof, reference being had to theaceompanying drawings', and to the letters of reference marked thereon, making apart of this specification. Y In the. annexed drawings, A represents a square pipe, made in the form of a circle, and thro'ugh which passes the'stovezpipe B, The ppeB has two smallA horizontal tubes D and E within the 'inner cireleof the radiator A.. C represents a. oonicahshuped tube, extending from the tube D to the lower tube E. and opening'v iutovit, hasgingfits largerrop'ening at the thhe D. Itnill he seen that the pipe B extends both belowlarnd above the outercircumferenee of the radiator4 pipe A, and ,is provided with n, suitabledanxperG, at the top. This invention is, by ineens o'its pipe B, attached to the stove in the usual manner, and when the damper G is open allows' the' products o -eombustiouto freely pass up the pipe B outside ofthe cone O around the tube D and up theehimney. It will be seen that the top of the` cone or ar-cha`mhcr C is notas' large as the inner circumference of the pipe, so there is au openingaroundit for the draught to pass up the ehimnex. The cold air having free access, enters at both'sifles ofthe small tube E, passes into the cone C, where, becouringtherein heated, it expands with the shape of' the cone and rsesithrough theopening X in the tube D,'strikingthe top ol' tuhe, eirculates through the room. It Will-thus bcseen that there is n continual current of nir passing in und out the c one. Having thus fully described my invention, what I claim ns new, and desire to secure hy Letters Patent, is- 'The arrangementof 'the annular radiator A and pipo B, provided with its tubes D E, and conical pipe C,

in the manner substantially as and for -thepurposes set forth.

In testimony that I eliln' the foregoing I have hereunto ser. my hand and scal-tl1is13t`n dnynfFebrunry, 1857,
